MawlamyinegyunnConstruction of fruit preservation warehouseBefore operation, these general machinery manufacturing knowledge still need to be known

Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at 33~35 kg / cubic meter. Therefore, it is usually recommended that the number of thermostat refrigeratory outlets should be 22~23 square / ton.

Reasonable space: the power consumption of the cold storage is calculated according to the cold consumption of the cold storage, which usually includes two parts: the cold consumption during cargo cooling and refrigeration; It is the cooling consumption of the refrigeration room itself and operation management.

Mawlamyinegyunn.The ground should be flat and not uneven. If the ground is uneven, the ground of the warehouse must be leveled before the cold storage can be built and installed.

Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, strict testing, quality assurance. Preferential activities are in progress. Welcome to consult. It has a good heat insulation effect. Then, the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore, it is necessary to be careful to select extensional perlite as cold storage.

.In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, these general machinery manufacturing knowledge still need to be known' >

The construction structure of structural cold storage can be brick concrete structure or steel structure, which can be determined according to their own budget and actual needs. At present most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform,MawlamyinegyunnConstruction of fruit preservation warehouse, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.

The volume of cold storage the size of cold storage shall be calculated according to the volume occupied by the stacking of goods stored in the cold storage, the indoor space between the stack and the wall, and the gap between the ceiling and the packaging room. After determining the volume, the length width ratio of the cold storage shall be determined. When designing the cold storage, necessary auxiliary engineering buildings and equipment should also be considered, such as working intermediate, packaging and combing room, special tool warehouse and loading and unloading platform, so as to ensure the quality of the cold storage.

Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every 1 ℃ increase in the evaporation temperature of the cold storage can save energy by 2 ~ 5. Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.

Quality recommendation.All wiring shall be neat. All switches and keys shall be opened and closed sensitively, reliably and accurately. Special connectors shall be used for wiring, and power protection shall be provided for the box and each power branch.

However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.

Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is, the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, these general machinery manufacturing knowledge still need to be known' >

During the production of cold storage, the cold storage will produce fixed length, width and thickness according to the needs of various cold storage projects. Generally 10cm thick cold storage plates are selected for high and medium temperature cold storage. The requirements for cold storage engineering plates of low-temperature storage and quick-frozen storage will be higher. Professional cold storage installation, installation, construction, fruit fresh-keeping cold storage and medical cold storage ensure the quality, Guarantee service. Guarantee quality. Your satisfaction is our pursuit! Welcome to inquire. In this case, use 12cm or 15cm thick library board. When you budget the cold storage project, you can make a reservation according to the specific conditions of your cold storage temperature. If you don't make a reservation for the cold storage plate, you should pay attention to the density of the cold storage plate and the thickness of the steel plate when purchasing the cold storage plate. According to the regulations, the cold storage shall be distributed

supply.For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least 15cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of 150 ~ 200mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of 100 ~ 150mm can be laid in the high-temperature cold storage.

Disadvantages: high precision requirements,MawlamyinegyunnHow much is a cold storage, shape and position tolerances are in micron level; No exhaust valve, poor off design performance; The working chamber is not easy to implement external cooling, and the heat in the compression process is difficult, so it can only compress the gas with small adiabatic index or internal cooling; Large displacement scroll refrigeration unit is difficult to realize. The receiving teeth are high, the displacement is large, the diameter is large, and the unbalanced rotation mass increases.

Installation of refrigeration equipment. The refrigeration system of the cold storage includes evaporator and units outside the cold storage. All equipment shall be installed in accordance with the construction specifications, and corresponding protection measures shall be taken for the installed equipment.
